Description

L'invention concerne la fixation d'appareils et notamment d'appareils électriques sur des profilés supports, à bords parallèles sortants ou rentrants tels que par exemple les profilés EN 50035 (profilé G) et EN 50022 (profilé chapeau).The invention relates to the attachment of devices and in particular electrical devices to support profiles, with outgoing or re-entrant parallel edges such as, for example, profiles EN 50035 (profile G) and EN 50022 (hat profile).

Il existe de nombreux dispositifs de fixation pour des appareils électriques tels que par exemple bornes de connexion, disjoncteurs, blocs de jonction, dispositifs qui comportent des crochets généralement élastiques pour permettre la pose ou la dépose de l'appareil sur le profilé support.There are many fixing devices for electrical devices such as for example connection terminals, circuit breakers, terminal blocks, devices which include generally elastic hooks to allow the installation or removal of the device on the support profile.

Ces dispositifs, qui font généralement partie de l'appareil sont situés à une extrémité ou base du boîtier de l'appareil, ce boîtier étant en matériau isolant. Les crochets sont bien évidemment en même matériau que le boîtier, le matériau devant permettre une certaine élasticité des crochets.These devices, which are generally part of the device, are located at one end or base of the device case, this case being made of insulating material. The hooks are obviously of the same material as the housing, the material having to allow a certain elasticity of the hooks.

Un inconvénient de ces dispositifs de fixation réside dans le fait que les crochets peuvent casser, ce qui rend impossible la fixation de l'appareil et rend celui-ci inutilisable.A disadvantage of these fixing devices lies in the fact that the hooks can break, which makes it impossible to fix the device and makes it unusable.

Un autre inconvénient réside dans le fait que le boîtier de l'appareil doit être en matériau isolant permettant une certaine élasticité au niveau des crochets, ce qui interdit l'emploi de matériaux isolants thermodurcissables tels que par exemple, certaines résines polyesters, les mélanines phénol, ou la matière connue sous la marque "La Bakélite".Another disadvantage lies in the fact that the housing of the device must be made of insulating material allowing a certain elasticity at the level of the hooks, which prohibits the use of thermosetting insulating materials such as for example, certain polyester resins, the melanins phenol. , or the material known under the brand name "La Bakélite".

L'invention a pour but un dispositif de fixation d'un appareil sur profilés supports dans lequel les crochets sont rigides, le boîtier étant en un matériau thermodurcissable ou non.The object of the invention is a device for fixing an apparatus on support profiles in which the hooks are rigid, the housing being made of a thermosetting material or not.

L'invention concerne un dispositif de fixation permettant de fixer un appareil, de manière amovible, indifféremment sur un profilé symétrique par exemple du type EN 50022 dit profilé chapeau, ou sur un profilé asymétrique par exemple du type EN 50035 dit profilé G.The invention relates to a fixing device making it possible to fix an appliance, in a removable manner, either on a symmetrical profile, for example of the type EN 50022 said hat profile, or on an asymmetrical profile for example of the type EN 50035 said profile G.

L'invention a pour objet un dispositif de fixation d'un appareil sur profilés supports, de type symétrique ou asymétrique, situé sur une base d'un boîtier isolant de l'appareil et comportant des crochets pour la fixation de l'appareil sur un profilé, caractérisé par le fait qu'il comporte une patte rigide, une pièce d'accrochage et un ressort à compression, que la patte est située à proximité d'un bord de la base et fait partie de ladite base, que la pièce d'accrochage comporte un corps, un premier .et un deuxième crochets rigides, et une tige prolongeant le corps et ayant une hauteur inférieure à celle du corps, la tige et le corps déterminant des épaulements, que le premier crochet est situé à une extrémité du corps opposé à la tige, que le deuxième crochet est situé entre le premier crochet et la tige, que la base comporte du côté de la patte un premier et un second logements, le premier logement ayant une hauteur égale à celle du corps et une longueur telle que le ressort à compression y est monté partiellement comprimé, le second logement faisant suite au premier logement et ayant une hauteur égale à celle de la tige, que la base comporte en extrémité un guide longitudinal pratiqué entre deux faces de la base et communiquant avec le premier logement, et que la tige est munie d'une goupille au delà du ressort à compression qui est comprimé dans le premier logement dans chaque cas de montage sur un profilé.The subject of the invention is a device for fixing an appliance to support profiles, of the symmetrical or asymmetrical type, situated on a base of a housing which insulates the appliance and comprising hooks for fixing the appliance to a profile, characterized in that it comprises a rigid tab, a hooking piece and a spring compression, that the tab is located near an edge of the base and is part of said base, that the attachment piece comprises a body, a first .and a second rigid hooks, and a rod extending the body and having a height less than that of the body, the rod and the body determining the shoulders, that the first hook is located at one end of the body opposite to the rod, that the second hook is located between the first hook and the rod, than the base comprises on the side of the tab a first and a second housing, the first housing having a height equal to that of the body and a length such that the compression spring is mounted there partially compressed, the second housing following the first housing and having a height equal to that of the rod, that the base comprises at the end a longitudinal guide formed between two faces of the base and communicating with the first housing, and that the rod is provided with a pin beyond the compression spring n which is compressed in the first housing in each case of mounting on a profile.

L'invention sera bien comprise par la description qui va suivre d'un exemple de réalisation illustré par les figures annexées dans lesquelles :

  • - La figure 1 est une vue en perspective éclatée d'un dispositif de fixation de l'invention,
  • - la figure 2 est une vue en élévation d'un élément du dispositif de la figure 1,

  • - la figure 5 représente le dispositif de la figure 1 monté sur un profilé symétrique dit profilé chapeau,
  • - la figure 6 représente le dispositif de la figure 1 monté sur un profilé asymétrique.
The invention will be better understood from the following description of an exemplary embodiment illustrated by the appended figures in which:
  • FIG. 1 is an exploded perspective view of a fixing device of the invention,
  • FIG. 2 is an elevation view of an element of the device in FIG. 1,
  • FIG. 3 is a left view of the element in FIG. 2,

  • FIG. 5 represents the device of FIG. 1 mounted on a symmetrical profile, said hat profile,
  • - Figure 6 shows the device of Figure 1 mounted on an asymmetrical profile.

Le dispositif de fixation, représenté figures 1 à 6, est constitué par une base 1 d'un boîtier d'un appareil à fixer, une pièce d'accrochage 2, un ressort à compression 3 et une goupille 4.The fixing device, shown in FIGS. 1 to 6, consists of a base 1 of a housing of a device to be fixed, a hooking piece 2, a compression spring 3 and a pin 4.

La base 1 comporte près d'un bord une patte 5 qui forme un coin 6 avec une face inférieure 7 de la base, ledit coin étant tourné vers le bord opposé de la base ; la patte 5 comporte une encoche 8 tournée vers l'extérieur de la base. Un premier logement 9 ménagé dans l'épaisseur de la base du côté de la patte 5 reçoit le ressort à compression 3 qui est comprimé partiellement, la longueur du premier logement étant inférieure à la longueur du ressort à compression non comprimé et supérieure à celle du ressort à compression comprimé totalement. Le premier logement 9 est prolongé, du côté de la patte 5 par un second logement 10 dont le rôle sera précisé plus loin ; ce second logement est également ménagé dans l'épaisseur de la base et sa hauteur est inférieure à celle du premier logement.The base 1 has near one edge a tab 5 which forms a corner 6 with a lower face 7 of the base, said corner being turned towards the opposite edge of the base; the tab 5 has a notch 8 facing outwards from the base. A first housing 9 formed in the thickness of the base on the side of the tab 5 receives the compression spring 3 which is partially compressed, the length of the first housing being less than the length of the uncompressed compression spring and greater than that of the fully compressed compression spring. The first housing 9 is extended, on the side of the tab 5 by a second housing 10 whose role will be explained below; this second housing is also formed in the thickness of the base and its height is less than that of the first housing.

La pièce d'accrochage 2 comporte un corps 11 qui se prolonge d'un côté par une tige 12, un premier crochet 13 situé à une extrémité du corps opposée à la tige, un deuxième crochet 14-situé entre le premier crochet et la tige, et un guide 15 sur une face du corps et sur une partie de la longeur du corps, à l'opposé de la tige 12. La tige 12 comporte un trou 16 dans lequel la goupille 4 est engagée lorsque le dispositif de fixation est monté. Le premier crochet 13 comporte une encoche 17 et une arête 28 tournées vers la tige 12, et le deuxième crochet 14 comporte une encoche 18 et une arête 29 tournées vers le premier crochet 13.The attachment part 2 comprises a body 11 which is extended on one side by a rod 12, a first hook 13 located at one end of the body opposite the rod, a second hook 14-located between the first hook and the rod , and a guide 15 on one face of the body and on a part of the length of the body, opposite the rod 12. The rod 12 has a hole 16 in which the pin 4 is engaged when the fixing device is mounted . The first hook 13 has a notch 17 and an edge 28 facing the rod 12, and the second hook 14 has a notch 18 and an edge 29 facing the first hook 13.

La tige a une hauteur inférieure à celle du corps 11 dont l'extrémité prolongée par la tige forme un épaulement 19 de chaque côté de la tige. La hauteur du corps 11 est au moins.égale au diamètre du ressort à compression 3 et égale à celle du premier logement 9. La distance entre les épaulements 19 et le trou 16 est au moins égale à la longueur du premier logement 9 de la base ; une lumière 20 est ménagée au fond des logements 9 et 10 pour le passage de la goupille 4.The rod has a height less than that of the body 11 whose end extended by the rod forms a shoulder 19 on each side of the rod. The height of the body 11 is at least equal to the diameter of the compression spring 3 and equal to that of the first housing 9. The distance between the shoulders 19 and the hole 16 is at least equal to the length of the first housing 9 of the base ; a light 20 is provided at the bottom of the housings 9 and 10 for the passage of the pin 4.

La figure 4 qui est une vue de dessous de la base selon une coupe IV-IV de la figure 2, représente l'extrémité de la base dans laquelle des évidements ont été faits de manière à ne laisser que les blocs 21, 22 et 23 ; le bloc 22 détermine avec les blocs 21 et 23, un guide longitudinal 24 dans lequel la pièce d'accrochage coulisse. Le guide longitudinal est donc situé dans l'épaisseur de la base entre deux faces 35 et 36 de celle-ci. Les évidements à l'extrémité de la base ont été faits dans le seul but de faciliter le démoulage du boîtier, dont la base 1 r fait partie, lors de sa fabrication. Une paroi du fond 25 du second logement 10 est situé dans l'alignement du bloc 22 de sorte qu'une face de la tige 12 de la pièce d'accrochage 2 vient contre cette paroi 25 qui constitue ainsi une extrémité du guide longitudinal 24. La lumière 20 pratiquée au fond des premier et second logements donc dans la paroi 25 et une paroi 26 du fond du premier logement permet le passage de la goupille 4 et son déplacement longitudinal lorsque la pièce d'accrochage 2 coulisse. Le bloc 21 comporte une rainure 27 dans laquelle coulisse le guide 15 de la pièce d'accrochage 2 ; cette rainure 27 coopère donc avec le guide 15 pour empêcher tout autre mouvement que le coulissement de la pièce d'accrochage 2.Figure 4 which is a bottom view of the base in section IV-IV of Figure 2, shows the end of the base in which recesses have been made so as to leave only the blocks 21, 22 and 23 ; the block 22 determines with the blocks 21 and 23, a longitudinal guide 24 in which the attachment piece slides. The longitudinal guide is therefore located in the thickness of the base between two faces 35 and 36 thereof. The recesses at the end of the base were made for the sole purpose of facilitating demoulding of the housing, including the base 1 r is part, during its manufacture. A bottom wall 25 of the second housing 10 is located in alignment with the block 22 so that one face of the rod 12 of the attachment piece 2 comes against this wall 25 which thus constitutes one end of the longitudinal guide 24. The light 20 formed at the bottom of the first and second housings therefore in the wall 25 and a wall 26 of the bottom of the first housing allows the passage of the pin 4 and its longitudinal displacement when the attachment part 2 slides. The block 21 includes a groove 27 in which the guide 15 of the attachment part 2 slides; this groove 27 therefore cooperates with the guide 15 to prevent any movement other than the sliding of the attachment part 2.

De cette manière la pièce d'accrochage 2, une fois montée dans la base, est maintenue dans le guide 24 son seul déplacement possible étant un déplacement longitudinal par coulissement dans la base ; ce déplacement est limité par la goupille 4 dans le sens de l'extraction de la pièce d'accrochage qui est ainsi imperdable.In this way the attachment part 2, once mounted in the base, is held in the guide 24 its only possible displacement being a longitudinal displacement by sliding in the base; this movement is limited by the pin 4 in the direction of extraction of the attachment piece which is thus captive.

Le montage du dispositif de fixation s'effectue de la manière suivante, le dispositif de fixation monté étant représenté figures 5 et 6.The mounting of the fixing device is carried out as follows, the mounted fixing device being shown in FIGS. 5 and 6.

Le ressort à compression 3 est introduit dans le premier logement 9 dans lequel il est partiellement comprimé; la tige 12 est introduite dans le guide longitudinal 24 du côté du bloc 21 ; par coulissement de la pièce d'accrochage 2 la tige 12 traverse le ressort à compression 3 et le guide 15 vient dans la rainure 27. En pressant sur le premier crochet 13, les épaulements 19 de la pièce d'accrochage 2 viennent au contact du ressort à compression 3 qui est ainsi comprimé ; le trou 16 de la tige 12 est donc éloigné du ressort à compression 3 ce qui permet d'y introduire la goupille 4. En relâchant la pression sur le premier crochet 13, le ressort à compression 3 repousse la pièce d'accrochage jusqu'à ce que les épaulements 19 sortent du premier logement 9 ; la goupille 4 est alors pratiquement au contact du ressort à compression 3.The compression spring 3 is introduced into the first housing 9 in which it is partially compressed; the rod 12 is introduced into the longitudinal guide 24 on the side of the block 21; by sliding of the attachment part 2 the rod 12 passes through the compression spring 3 and the guide 15 comes into the groove 27. By pressing on the first hook 13, the shoulders 19 of the attachment part 2 come into contact with the compression spring 3 which is thus compressed; the hole 16 of the rod 12 is therefore distant from the compression spring 3 which allows the pin 4 to be inserted therein. By releasing the pressure on the first hook 13, the compression spring 3 pushes the attachment piece up that the shoulders 19 come out of the first housing 9; the pin 4 is then practically in contact with the compression spring 3.

La figure 5 représente le dispositif de fixation de l'invention monté sur un profilé symétrique dit profilé chapeau. Le montage s'effectue de la manière suivante. Une aile 30 du profilé étant engagée dans le coin 6 de la patte 5, une extrémité de l'autre aile 31 du profilé vient au contact de l'arête 28 du premier crochet 13 ; en exerçant sur la base 1 une pression dirigée vers le profilé, l'arête 28 glisse sur l'extrémité de l'aile 31, et la pièce d'accrochage 2 se déplace vers la gauche de la figure 5 entraînant la compression du ressort à compression 3 par la goupille 4. Lorsque l'extrémité de l'aile 31 est engagée dans l'encoche- 17 la pièce d'accrochage est rappelée vers la droite par l'action du ressort à compression 3 sur la goupille 4. Comme représenté sur la figure 5, l'extrémité de l'aile 31 étant en butée au fond de l'encoche 17, la pièce d'accrochage 2 ne reprend pas sa position de repos, le ressort à compression 3 étant encore comprimé et n'occupant pas toute la longueur du premier logement 9. De cette manière le ressort à compression 3 exerce, par l'intermédiaire de la goupille 4, une force de rappel sur la pièce d'accrochage 2, force qui applique le premier crochet 13 sur l'aile 31 du profilé. Pour dégager la base 1 du profilé on engage un outil, tel qu'un tournevis par exemple, dans une encoche 32 du premier crochet 13 afin de déplacer la pièce d'accrochage 2 vers la gauche et libérer ainsi l'aile 31 du profilé par pivotement de la base par rapport à l'aile 30.FIG. 5 shows the fixing device of the invention mounted on a symmetrical profile called a cap profile. The assembly is carried out as follows. A wing 30 of the profile being engaged in the corner 6 of the tab 5, one end of the other wing 31 of the profile comes into contact with the edge 28 of the first hook 13; by exerting on the base 1 a pressure directed towards the profile, the edge 28 slides on the end of the wing 31, and the hooking piece 2 moves to the left of FIG. 5 causing the compression of the spring to compression 3 by the pin 4. When the end of the wing 31 is engaged in the notch 17 the hooking part is returned to the right by the action of the compression spring 3 on the pin 4. As shown in FIG. 5, the end of the wing 31 being in abutment at the bottom of the notch 17, the attachment part 2 does not return to its rest position, the compression spring 3 being still compressed and not occupying not the entire length of the first housing 9. In this way the compression spring 3 exerts, by means of the pin 4, a restoring force on the attachment part 2, a force which applies the first hook 13 to the wing 31 of the profile. To release the base 1 from the profile, a tool, such as a screwdriver, is engaged in a notch 32 of the first hook 13 in order to move the attachment piece 2 to the left and thus free the wing 31 from the profile by pivoting of the base relative to the wing 30.

On peut également presser la base 1 selon la flèche F de manière à comprimer le ressort à compression 3 puisque la goupille 4 est fixe par rapport au premier crochet 13 ; on dégage ainsi l'aile 30 du profilé du coin 6 par pivotement de la base par rapport à l'aile 31.It is also possible to press the base 1 along the arrow F so as to compress the compression spring 3 since the pin 4 is fixed relative to the first hook 13; the wing 30 is thus released from the profile of the corner 6 by pivoting of the base relative to the wing 31.

La figure 6 représente un dispositif de fixation de l'invention monté sur un profilé asymétrique. Une aile 34 du profilé est engagée dans l'encoche 8 de la patte 5 ; l'extrémité de l'autre aile 33 du profilé vient en contact avec l'arête 29 du deuxième crochet 14 ; en exerçant sur la base 1 une pression dirigée vers le profilé, l'arête 29 glisse sur l'extrémité de l'aile 33 et la pièce d'accrochage 2 se déplace vers la droite de la figure 6, entraînant la compression du ressort à compression 3 par l'intermédiaire des épaulements 19. Lorsque l'extrémité de l'aile 33 est engagée dans l'encoche 18, la pièce d'accrochage 2 est rappelée vers la gauche par l'action du ressort à compression 3 sur les épaulements 19. Comme représenté figure 6, l'extrémité de l'aile 33 étant en butée au fond de l'encoche 18, la pièce d'accrochage 2 ne reprend pas sa position de repos, le ressort à compression étant encore comprimé et n'occupant pas toute la longueur du premier logement 9. De cette manière le ressort à compression 3 exerce sur la pièce d'accrochage 2 et par l'intermédiaire des épaulements 19, une force dirigée vers la gauche, force qui applique le deuxième crochet 14 sur l'extrémité de l'aile 33 du profilé.Figure 6 shows a fixing device of the invention mounted on an asymmetrical profile. A wing 34 of the profile is engaged in the notch 8 of the tab 5; the end of the other wing 33 of the profile comes into contact with the edge 29 of the second hook 14; by exerting on the base 1 a pressure directed towards the profile, the edge 29 slides on the end of the wing 33 and the attachment piece 2 moves to the right of FIG. 6, causing the compression of the spring to compression 3 via the shoulders 19. When the end of the wing 33 is engaged in the notch 18, the attachment piece 2 is biased to the left by the action of the compression spring 3 on the shoulders 19. As shown in FIG. 6, the end of the wing 33 being in abutment at the bottom of the notch 18, the attachment part 2 does not not return to its rest position, the compression spring being still compressed and not occupying the entire length of the first housing 9. In this way the compression spring 3 exerts on the attachment part 2 and through the shoulders 19, a force directed to the left, a force which applies the second hook 14 to the end of the wing 33 of the profile.

Pour dégager la base 1 du profilé, il suffit de presser sur' le premier crochet 13 ce qui entraîne le déplacement vers la droite de la pièce d'accrochage 2 donc du deuxième crochet 14, et libére ainsi l'aile 33 du profilé.To disengage the base 1 from the profile, it suffices to press on the first hook 13 which causes the displacement of the attachment part 2 therefore of the second hook 14, and thus frees the wing 33 from the profile.

On remarquera que dans le dispositif de fixation de l'invention le ressort à compression 3 qui est monté comprimé en partie dans le premier logement 9 travaille de la même manière pour les deux types de profilés, c'est-à-dire qu'il subit une compression lorsque la base est montée sur le profilé ; dans les deux cas le crochet coopérant avec le profilé est soumis à une force dirigée vers l'aile du profilé en contact avec le crochet.It will be noted that in the fixing device of the invention the compression spring 3 which is mounted compressed in part in the first housing 9 works in the same way for the two types of profiles, that is to say that it undergoes compression when the base is mounted on the profile; in both cases the hook cooperating with the profile is subjected to a force directed towards the wing of the profile in contact with the hook.

La pièce d'accrochage 2 qui coulisse dans le guide longitudinal 24 ménagé dans l'épaisseur de la base 1 peut être en même matériau que ladite base, ou, si pour des raisons mécaniques par exemple, le guide longitudinal a une largeur faible, en métal.The attachment piece 2 which slides in the longitudinal guide 24 formed in the thickness of the base 1 can be made of the same material as said base, or, if for mechanical reasons for example, the longitudinal guide has a small width, in metal.

Les logements 9 et 10 peuvent également traverser de part en part la base 1 sans que l'on sorte pour autant du cadre de l'invention.The housings 9 and 10 can also pass right through the base 1 without departing from the scope of the invention.

Dans le dispositif de l'invention, dont un exemple de réalisation vient d'être décrit, la patte 5 et les crochets 13, 14 sont rigides, la fixation du boîtier sur un profilé ne nécessitant aucune élasticité des crochets ou de la patte, de sorte que même s'ils sont réalisés en matériau relativement souple, ils soient dimensionnés pour ne pas être élastiques.In the device of the invention, an embodiment of which has just been described, the lug 5 and the hooks 13, 14 are rigid, the fixing of the housing to a profile requiring no elasticity of the hooks or the lug, of so that even if they are made of relatively flexible material, they are dimensioned so as not to be elastic.

. Le fait que les crochets et la patte ne soient pas élastiques permet de réaliser les boîtiers des appareils à l'aide de matériaux thermodurcissables.. The fact that the hooks and the tab are not elastic enables the housings of the apparatuses to be produced using thermosetting materials.
